Hi again, We've just upgraded to 12GB of ram and are still experiencing extremely high context switches, in some cases, 45000 (vmstat 3 100). Does anyone have a link to a technical doc that has information specifically dealing with context switching and RAM optimization? I'm thinking that I just need to give more cpu time to kswapd. Comments? Thanks.
